Luggage and bags:
Unless you have come straight from the Inca Trail you won't need to bring a whole lot of stuff with you. There is a bag storage room (with security) that you can leave your bags at if you like - perfect if you've just come off the Inca Trail. Just a small bag with film, camera and water should suffice.
Toiletries and Medical Supplies: Suncreen and a hat are a must as you are much closer to the sun!!
Luggage and bags:
Packing as lightly as possible will make the hike a lot easier on you. It is amazing how much more difficult a 50 km hike can be with 20 kg in you pack.
Clothing/Shoes/Weather Gear: 1 good comfortable pair of hiking boots, and rain gear, long pants (zip offs are good) a long sleeve shirt and t-shirts. Bring as little clothes as you feel comfortable with it will make it a lot easier.
Toiletries and Medical Supplies: A roll of toilet paper, sun screen, insect repellent
Photo Equipment: Film, film and more film! Extra batteries since the llamas tend not to sell batteries on the trail.
Camping/Beach/Outdoor Gear: You can bring you own sleeping bag, or rent one from most companies who offer the tour (or other companies in Cusco)
Miscellaneous: Mineral water (the container is more important as you keep refilling it on the hike) also buying one of the water bottle holders in Cusco worked well for me. A flash light which you will need for the hike to MP at sunrise. Sunglasses, a sun hat, a knife, emergency money (recommended $50 US) in case you have to hire a porter to carry you bag or need to be taken back to the camp (injury). Your Passpot (original, not sure why, but it was asked for. Probably good idea to keep in a ziploc bag.
Luggage and bags:
Your equipment is very important when you go on the Inca trail.
A good and comfortable backpack is a must because you will carry it for 6 to 8 hours each day. And don’t take all your belongings with you on the trip, think before you start and leave all the not needed items in your hostel. It’s a big difference between a backpack of 7 kilo’s and one of 12 kilo’s. One advice is to use the same hiking clothes everyday, you will smell just like the others so that doesn’t matter. Make also sure your backpack is fitted properly, or you will feel it in your shoulders and back the next days.
The weather can be very hot or you can have cold rain showers, so make sure that you can change quickly into the right gear, have a poncho and rain jacket in the top of your backpack and not in the bottom.
Clothing/Shoes/Weather Gear: First of all you need good hiking boots because you are travelling 32 km over rough terrain. Also dress in layers and foresee clothes for hot and cold rainy weather.
Camping/Beach/Outdoor Gear: During the day it can be very hot and during the night it will be against freezing point or even below zero (depending on the time of the year) so dress in layers and make sure that you have a good sleeping bag and a good mat to lay on. Because you have to keep the cold from the ground out of your sleeping bag.
Miscellaneous: Carry plenty of water with you, the company provides you boiled water with a twist of thee, but you shall have to determine how much you need for the whole day. Take somewhere between the 1,5 and 3 litres with you. They stop for lunch and there you get some food and drinks.
Buy a wooden walking stick and a plastic poncho, these are also good investments for the few peso that you have to pay. Also good to have is a carrier for your water bottle that you can hang over your shoulders, so that you don’t need to get that water bottle out of your backpack each time you need a drink.
And don’t forget your hat, sunglasses, sun-crème and toilet paper, because during the trail the only toilets you will see are at the campsites so you will have the whole free nature to your disposal.
